CH2PhPhenylalanine a ribose sugar. This is located outside

CH2PhPhenylalanine is an amino acid which changes into tyrosine in the body and this then helps to make proteins and brain chemicals to function.  L-phenylalanine is located in proteins this a dietary souces and foods such as fish meet cheese eggs and milk contain phenyalanine. -CH2CONH2Asparagine is one of the most common natural amino acids. As the side chain’s functional group is has a carboxamide. This amino acids is not an important amino acid. When asparagine and another source of carbonyl is reacted with each other and heated to sufficient temperature it produces acrylamide in food. These products are found in foods such as chips, toasted breads. Asparagine side chains can form hydrogen bond interactions with the polypeptide backbone. The residues of asparagine are often found near the beginning ad the end of alpha helices and in beta sheet. Asparagine’s role can be said as a lid or cap of the hydrogen bond. Asparagine is essential for the human body. Mainly its function is very essential for the development and growth of brain.                  There are two types of nucleic acid. DNAstands for Deoxyribonucleic acid. DNA stores genetic information of a person which tells about their inherited characteristics which are passed on from their parents. The DNA has the code for making proteins. DNA is found in the nucleus of cells. Covalent phosphodiester bonds holds all the molecules together in a DNA. The DNA contains subunits which repeat and those subunits are called monomers or nucleotides. Nucleotides has 3 main parts a negative charged phosphate group which has the bases of bases of A, C, G and T, second part of the nucleotides is sugar which is also called deoxyribose and 3rdpart is a nitrogen base, the DNA contains 4 nitrogen bases. The structure of the DNA is also known as double-helix.  RNA: is single stranded nucleic acid. Which can be the genetic material. There can be 3 different type of RNA- mRNA, rRNA, tRNA. Among them all rRNA is the most predominant type. mRNA is negatively charged at neutral pH.    RNA is small with hundreds to thousands of nucleotides. It has a ribose sugar. This is located outside the nucleus in the cytosol and ribosomes. Makes proteins inside the ribosomes. RNA make up our genes which we pass through the generations. RNA is a charged molecule due to the phosphate group being negatively charged. The basic structure of this is about the same as the DNA it is basically half of the ladder of DNA. So it is quite similar to the DNA. This is a single standed chain whereas the dna is double helix.  SATURATED AND UNSATURATED FATTY ACIDSSaturated fatty acids has a long chain carbon – carbon – carbon- carbon- and there’s a single covalent bond in between every carbon and that is the reason as to why it is called saturated. The rest of the atoms involved are hydrogen. They are arranged in a zig zag pattern The carbon atoms each have the ability to make four chemical bonds so in fatty acid each carbon is using one bond to hold on to the carbon infront of it. This is not very suble in water and clogs arteries. Unsaturated fatty acids have at least one or more double bond. The more temperature of unsaturation, the lower the melting point of a fatty ac id. These are not as stable as the saturated fatty acids are.
