Nutrition Chapter 5
Besides containing atoms of carbon, hydrogen, and oxygen, proteins also contain? Nitrogen What are amino acids? Amino acids are compounds that contain one amino group, one carboxyl group, one hydrogen and one variant group that provides the individual characteristic, shape, charge, and size. They are the single units of proteins What are dipeptides, tripeptides, and […]

Amino Acids, Peptide Bonds, and Protein Structure
Amino Acids building blocks of proteins-is an organic molecule with both an amino group and a carboxyl group.-the general formula: at the center of the amino acid is an asymmetric carbon atom called the alpha carbon. Its four different partners are an amino group, a carboxyl group, a hydrogen atom, and a variable group symbolized […]
Structure and Synthesis of Proteins
Amino Acid building blocks of proteins– Central carbon (alpha) atom connected by covalent bonds to:– amino group (-NH2)– carboxyl group (-COOH)– H atom– side chain (R group) Hydrophobic Amino Acids typically have nonpolar R groups; amino acids with long alkyl side chains. Alanine, Leucine, Isoleucine, Valine, Phenylalanine. More likely to be found in the interior […]

Terms in this set (15) OriginalAlphabetical Proteins are formed by linking basic building blocks together. These building blocks are called ‘amino-acids’, and there are ~20 different kinds of amino-acids. The first step is: Formation of amino-acid building blocks Second step is: Joining amino-acids into a polymer like beads on a string (this order is the […]
