cellulose and starch

• cellulose is made up of beta glucose
• in cellulose every second beta glucose is flipped
• beta glucose in cellulose makes 1,4 glyosidic bonds
• microfibrils are made up of 60 to 70 cellulose
• cellulose are long straight unbranched chains
• strength is added by sticking microfibrils together by pectin or hemicellulose
• starch is made up of alpha glucose
• starch is a store of energy while cellulose is used for plant structure
• strach is made up of 1,4 and 1,6 glyosidic bonds while cellulose only has 1,4
• starch is chemically unreactive, compact, insoluble
• cellulose is insoluble and biodegradable
