BIOL 101 Lecture Notes - Lecture 5: Hydrophile, Phospholipid, Beta Sheet
Document Summary
Which are made of alpha and which of beta glucose: Chitin is a structural component in the exoskeletons of animals and the cell walls of fungi. Phospholipid: structural component of the cell membranes"s structure (lipid bilayer). Hydrophillic heads and hydrophobic tails keep the membrane intact. Steroid: hormones and membrane fluidity regulators in cell membrane. Triacylglycerols: utilized as an energy source; a storage form of triacyleglycerides. Draw the general structure of an amino acid with all bonds and atoms. What kind of bonds can be formed by: The primary structure of a protein is the sequence of amino acids in a polypeptide chain. They are held together by covalent peptide bonds. Two types of secondary structure are the alpha helixes and beta-pleated sheets. Alpha helixes are held together by hydrogen bonds on every fourth amino acids, while beta pleated sheets are held together by hydrogen bonds between two parallel segments.
